The BEST dive hole in 2011 was the last one fashioned, just days before we pulled out of Explorers Cove. Named "the Stockton site" in honor of Dr. Bill Stockton, fellow Antarctic researcher, this hole was made overnight using two Hotsies operating simultaneously.
Laura serves as a scale marker next to the Stockton hole
Bill mapped the density of the Antarctic scallop Adamussium colbecki on the seafloor back in the late 70's/early 80's, and we repeated his survey to see if there have been any changes since that time. This hole exposed an area where Bill reported as many as 80 scallops per square meter -- a huge density.
I'll report back with the findings once they're published. (Hint: yup, there were changes ...)
